The mid-stage symptoms of rectal cancer are very obvious

The mid-stage of rectal cancer refers to the period between the early and late stages. At this time, the symptoms of mid-stage rectal cancer are already very obvious, and patients should pay more attention to their abnormalities. Let's ask experts to tell us in detail about the symptoms of mid-stage rectal cancer .

The mid-stage symptoms of rectal cancer are mainly manifested in the following aspects:

1. Symptoms of intestinal stenosis: Cancer invasion causes intestinal stenosis. Initially, the stool becomes deformed and thinner. When it causes partial intestinal obstruction, there are abdominal pain, bloating, hyperactive bowel sounds and other symptoms of incomplete intestinal obstruction.

2. Rectal irritation symptoms: frequent urge to defecate and change in bowel habits; a feeling of falling in the anus, tenesmus, and incomplete defecation before defecation, and lower abdominal pain in the late stage.

3. Symptoms of rectal ulcer infection: blood and mucus on the surface of the stool, even purulent blood in the stool. The frequency of symptoms is 80% to 90% blood in the stool, 60% to 70% frequent stool, 40% thin stool, 35% mucous stool, 20% anal pain, 20% tenesmus, and 10% constipation. Cancer invades the prostate and bladder, and frequent urination, dysuria, and hematuria may occur. Invasion of the presacral nerve may cause severe and continuous pain in the sacral coccyx. In the late stage, when liver metastasis occurs, there may be mid-stage symptoms of rectal cancer such as ascites, hepatomegaly, jaundice, anemia, weight loss, edema, and cachexia.

Patients in the middle stage of rectal cancer have obvious changes in bowel habits. The number of bowel movements per day can be as many as a dozen times. Most of them are loose stools or mucus stools. Mucus and blood stools or thick blood stools can also be seen. There is a clear sense of tenesmus. Some patients may have fresh blood in their stools. There is dull or heavy pain in the abdomen before and after each bowel movement. The digital examination of mid-stage rectal cancer can touch a cauliflower-like tumor with raised edges and ulcers in the middle. It is brittle and easy to bleed, and has a certain degree of mobility. Patients with this symptom should go to the hospital for treatment in time.
